Application filed October 27; 1915. Serial No. 58,280.

1 all whom it may concern: a

lie it known that I, LINUS I). ARMSTRONG, a citizen of the UnitedStates, and resident of the city of Providence, in the county ofProvidence and State of Rhode Island, have invented certain newand'useful Improvements in Cotton-Pickers, lowing is a specification.

This invention relates class adapted for use chines and the like,invention is to prov in cotton picking 1na-' and the ob] cot of thiside' sucha grid bar hav ing its two opposite working edges beveled,

whereby the bar may be reversed edge for edge to bring the fresh workingedge lnto operating position when the; first edge has been worn, therebydoubling the working tVith these and other objects in view, the

invention consists of certain novel features of construction, as will bemore fully described, and particularly pointed out in the appendedclaims.

In the accompanying 1- is a side elevation illustrating a gang of myimproved grid bars in operative position also showing the adjustingmeans. Fig. 2 is a section on line 2-2 of Fig. l, showingone end of agrid bar as pivoted in the frame and the fingers or pins of the slidingplate as engaging the grid bars for the purpose of ad- Fig. 3- is aperspective view of one of the grid bars. Fig. 4 is a perspective viewshowing, a portion of the sliding plate, for adjusting the angle of thegrid bars.

of receiving the grid bars, presently described. This frame is curve ofthat on which'the grid barsare with a clownwardlyextending ear in whichthe operating handle is pivoted at 16, see Fig. 2. The grid bars 17- areformed of flat stock which is 'of'a] width much greater thanjitsthickness both ends ofeach-bar is provided with-a short trunnion 18;"Anessential feai.nvention is that the opposite edges of each bar arebeveledas at 27 and 28- to a: thin'edge, v

This plate is also providedwith a downwardly extendthe working. life Another feature of mg sectionof toothed rack 21, which is engaged by the segment 22, pivoted at 16which segment is provided with an operating handle 23 A bolt 24, ispassed through a slot 25 in thesegment memb be readily set up, made, tofirmly retain the plate in adjusted position.

In the operation of this device the grid above de-' are lnserted 1n barsare beveled inthemanner scribed ,and their trunnions the openings. 13whereby the bars are spaced apart and pivotally mounted between theframes 10.- Thisslide'bar 19' with its little amount of foreign matterit contains, therefore it isv found advisable to provide means wherebythe'opening between the grid bars.

so that when one edge bars it is only may be varied to suit conditionsunder which the machine is operating, therefore when it is desired toreduce the space between" the necessary to carry the handle portion 23to the left until the bars are moved to the desired position after whichthe nut 26 ,is set up, and the whole remains set until adjustment isagain required.

I have shown and described one form of mechanism for adjusting the angleof the grid bars, but the details of this mechanism may be variedwithout departing from the spirit and scope of my invention. 1 have alsoshown the grid bars as formed with the opposite edges of each beveledthereby making each bar reversible whereby its working life may bedoubled and any means for accomplishing this object should be consideredas covered by this patent.

I claim: 1 i

,l. A. reversible grid bar comprisinga flat bar having both of itsopposite edges beveled to a thin working edge.

2. A reversible grid bar comprising a flat Copies of this patent may beobtained for five cen ts each, by addressing the bar havingeled onplanes substantially parallel to each other and each having" a thinworking edge, said bar being adaptedfto be reversed edge for edge.

3. A reversible grid bar comprising" a fiat bar having both of itsopposite edges beveled on planes substantially parallel to each othereach having a thin working edge, said bar being adapted to be reversededge for edge, and means whereby said bar may be rocked to adjust itsworking angle.

4:. A reversible grid bar comprising; a flat bar having; its oppositeedges beveled to a thin working edge, said bar being adapted to bereversed edge for edge, and a trunnion on the end of each bar wherebythe same may be rotatably mounted.
